This invention relates to spinning wheel devices such as used in spinning parallel bridge. cables, the objectof the inventionbeing to provide a more etlicient spinning wheel mounting whichfshall avoid the difliculties experienced with previous spinning wheel devices, especially inpassing obstacles or turning around guiding sheaves, ,and by which a higher spinning speed is made' practical.

use heretofore consistsy of two arms projecting sidewise from the traction rope by which they are driven and rto which they are clamped, these arms carrying bars forming' a V, with its base atthetraction rope, from ythe angle ofwhichprojects sidevvise a stud upon which the spinningwheel is mounted torotate freely in line with the traction rope. This f construction'results in a sidewisestrain upon the spinning device and slow speed 1s necessary'in passing traction ropesupports or turning curves at the ends of the run, result-` ing in a considerablereduction oi the spin- 7'- ping speed.

site sides of the ytraction rope andV .inclined outward and downward fromthe underside of thev traction rope, Vso as toprovide space for the spinning wheel supportv to run between them with the traction rope. This conf struction, also,-enables two spinning wheels tobe mounted on a. single frame for operation The spinning lwheel `mounting in general v the traction rope, `thus. ,practically doubhng the spinning capacity.

For a. full understanding of the invention,

' a detailed description of a construction of the preferred form embodyingk all the features of theinvention, will now be given in c0nnection Vwith the accompanying kdrawings forming a part ofthis specication and the features forming the invention then specifically pointed out in the claims.

In theV drawings k:-

Figure V1 is a side view of the spinning wheel device in` place on the traction rope, in the form suitable for use witha single spins ning` wheel; g

Figure 2 is across sectionon ktheline 2.0i Figure 1, looking in the direction of `the are row;

Figure 3 showsa modiiication withtwo spinning wheels, this View being an end elevation looking to the left as in Figure 1;

FigureA/is a detail cross ysection on the line 4 of Figure l.

n Referring now especiallyto Figures 1, 2 and 4, Ais the spinning wheel -over which' the strand loop passes for spinning ythe cable, as usual insuch operations, B4 the spinning wheel frame in which the spinning wheelfA is mounted, and C the end supports and D the intermediate f support lby which the wheel frame B is swung on the moving traction rope E.Y The frame B is a rigid framexformed in any suitable manner, being shown as a skele ton frame formed 0i angle bars to securefthe desired strength and rigidity, and at the bot-z tom of this frame the spinningl wheel A isy mounted to rotate freelyon a stud 10 project-k ing sidewise from the frame B. The frame VB is suspended by links 11 from the two end supports C, and has a pinV and vertical slot f connection 12 with the center support D,so

' that. by the swinging of the links 11 and its y vertical movement onl the pin andslot connection 12, the frameB accommodates'itself to the vertical curving of the traction rope E.

The end supports C and center support D are swung on the traction rope E by arms 13, which are formed at the end with split sleeves 3 so as to be readily applied to and removed from the traction rope E. Similar sleeves 14, shown in Figure 4, are clamped on the traction rope at such intervals as to permit the curving of the traction rope E while at the same time assuring the movement of the spinning wheel frame with the traction rope, and the spaces between the clamped sleeves 14 and the arms 13 and end sleeves 15 on the traction rope E preferably are filled by split sleeves 16, mounted loosely on the rope, thus permitting the curving of the traction rope while holding the supports C, D in position. The end sleeves l5 are preferably of rubber or other elastic material and tapered away from the spinning wheel frame as shown, so as to readily enter the space between guide pulleys and prevent shock. The halves of the split sleeves are held together by pins 4, as shown in Figure 4 and all the sleeves may be of the same construction except that sleeves 14 are formed to lock on the traction rope and the other sleeves are free to turn and slide on the rope. The end supports C are provided with a series of holes l and the top bar of the spinning wheel frame B is provided with a plurality of holes 1 to receive the pins 2 by which the links 11 are mounted in the frame B and supports C, so that the position of these links l1 connecting the frame B and f where in the spinning run is provided by the.

supports C and the position of the spinning wheel frame may be adjusted as desired, which may be important if the traction rope should stretch or the connections to the rope be not accurately positioned.

`The supports C, D, of the spinning wheel frame are vertically in line with the traction rope E, and the guiding and support of the traction rope around the end turns or elseinclined sheaves F on which the traction rope runs, these inclined sheaves F being separated below the traction rope sufficiently to permit the arms 13 and the supports C, D to pass between them.

InFigure 3, there is shown a construction in which two spinning wheels A, A are mounted on opposite sides of the frame G by stud 16 projecting on opposite sides of the frame, this frame G being of any suitable rigid construction and this frame G is suspended from the traction rope E by the same side and center supports C. D, links 11 and slotted connection 12 as in Figures 1 and 2.

It will be seen that the spinning wheel frame and spinning wheel or wheels thereon yare free to swing sidewise and move verticallykso as to accommodate themselves to anv bending of the traction rope E and readily pass such side obstacles as otherwise might slow up the spinning speed. The inclined guide s eaves, also, enable the spinning frame to be swung vertically in line with the traction rope while assuring the suitable guiding and support ot' the traction rope, thus securing a more direct and eiiicient pull of the traction rope upon the spinning frame and wheel. An increased spinning speed and greater certainty of operation is thus secured. The provision for two spinning wheels, also, is important where especially high spinning capacity is desired.

It will be understood that the invention is not limited to either of the specific constructions shown, but that the form and arrangement of the parts may be varied and man)` modifications made within the invention claimed.
